Whether fraud pertains to craftiness?

❌ Objection 1 : It would seem that fraud does not pertain to craftiness. For a man does not deserve praise if he allows himself to be deceived, which is the object of craftiness; and yet a man deserves praise for allowing himself to be defrauded, according to 1 Cor. 6:1, "Why do you not rather suffer yourselves to be defrauded?" Therefore fraud does not belong to craftiness.

❌ Objection 2 : Further, fraud seems to consist in unlawfully taking or receiving external things, for it is written (Acts 5:1) that "a certain man named Ananias with Saphira his wife, sold a piece of land, and by fraud kept back part of the price of the land." Now it pertains to injustice or illiberality to take possession of or retain external things unjustly. Therefore fraud does not belong to craftiness which is opposed to prudence.

❌ Objection 3 : Further, no man employs craftiness against himself. But the frauds of some are against themselves, for it is written (Prov. 1:18) concerning some "that they practice frauds [Douay: 'deceits'] against their own souls." Therefore fraud does not belong to craftiness.
